7 Years or so later and I'm actually going to upgrade, been putting it off due to all sorts of things, wasn't impressed with the RTX 2000 series, couldn't get an RTX 3080 on launch so gave up but finally got an RTX 4090 FE on launch day which has now inspired me to upgrade and rebuild the Project Nebula.
Going to keep posting here as it's been really useful for me to look back through the thread and see exactly what I did.
It will now become
Project Black hole as I am changing to ZMT and black PSU cables, some might say boring, but I have had enough of the bright circus colours.
Talking of colours the Mayhems Pastel is still working fine without any maintenance which is probably a testament to my OCD initial flushing with the Blitz kits and the quality of the Mayhems fluid.
You can see some UV discoloration on the tube but the fluid colours are still great.
Had to plug the 4090 into try it out while waiting for parts to arrive
When I strip everything down I imagine there will be some build up and gunk in places but as far as temps and flow rates go there has been no noticeable changes.
Going forward the system spec will be:
